Android: Part of the problem with smartphones is that the virtual keyboards they all come with take up a lot of screen space. Minuum skirts that problem with a crazy-accurate compressed keyboard.

Minuum, which began life as an IndieGogo campaign, shrinks most of the keyboard down to a near-single line, relying on an advanced prediction algorithm to reliably input text. Once you get used to it, it's pretty smooth. In the event that the tiny version doesn't work, the newest update to Minuum adds a traditional full-sized option that can be easily dismissed.
